A Modification of the RV-PA Conduit in the Sano to Reduce Conduit Obstruction

The RV-PA conduit or Sano modification, has recently been reintroduced into the Norwood armamentarium. Many centers, however, have been experiencing conduit obstruction with the Sano. This video demonstrates a modification of the technique used for the RV-PA conduit that has reduced the incidence of conduit obstruction at our institution. There has recently been a published report of the use of the ringed conduit for for the reduction in conduit obstruction. The technique described here proposes some other minor modifications, namely the insertion of the rings into the ventricular myocardium. This technique has dramatically reduced the incidence of conduit obstruction in our experience.
